I think it would be good to add an optional salary range field and then you could test how many people fill it in. You could even try and scrape existing posts to see who has put it in the description. Then you could allow candidates to filter/sort on it. Or even better, prioritise jobs with salary above those keeping it secret, highest at the top. We require a salary on Cleanweb Jobs and it hasn't put that many companies off. However, we're mainly UK focused and a lot of job ads already list a salary here.
